application and my 25,1912. serial No. 'unisa 'To al?, whom it may concern:

Be it known that I, GEORGE F. KEARNEY, a. citizen of the United States, residin at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Paper-Roll Holders, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to paper roll holders and its object is a simple and yinexpensive sup ort for rolls of pa er towels and other simllar rolls in which t e paper is in a continuous length and perforated at regular intervals whereby the portion desired for use may be readily separated from the roll and so arranged as to prevent the withdrawing or unwinding of more than a single sheet at cach actuation of the device. Heretofore in holders of this type it has been possible to unwind a greater portion than is needed at any one interval as no provision is ordinarily made to prevent a rotation of the roll after a specified portion has been unwound therefrom, and it is the purpose of this invention not only to overcome this obvious fault but also to provide a device in which the roll may not be removed from the spindie upon which it is mounted without the unwinding thereof, but that nevertheless is simple to remove the core therefrom after the roll has been unwound in the ordinary manner in use and insert a new roll. These and further objects and novelties of the invention are hereinafter more fully described and claimed and shown in the accompanying drawings in which- Figure l is a perspective view of a paper roll holder embodyingmy invention. Fig. E2 is a sectional view of the roll spindle illustrating more fully its structure and the method of mounting in the supportingr bracket.

Similar characters refer to similar parts throughout the drawings and specification.

1 indicates a bracket adapted to be secured to a wall or other convenient place which is provided with a depending arm 2 integrally formed therewith upon one end and upon tho opposite end is provided with a pivoted arm 3. The roll spindle 4 is preferably formed of wood and is provided at one end with a rod 5 having a spiral groove 6 formed in the surface thereof and the rod extends through a bearing 7 secured to or formed with the arm 2 which is provided with a pin Bengaging in the spiral groove.

The roll spindle 4 is less in length than the dist-ance between the two arms 2 and 3 and in a space between the arm 2 and the end of the spindle 4, and upon the shaft or rod 5, is a coil spring 9 tending to force the spindle away from the bracket 2. By pulling on the loose end of the paper on the roll, the roll is rotated which rotates the spindle fi and rod 5 and this rotation of the spindle and rod draws the roll toward the bracket 9.

by reason of engagement of the pin 8 in the spiral groove 9, and it is evident that this rotation may continue only until the spring 9 has been fully compressed.

The distance the paper roll may move endwise determines the amount of paper that may be withdrawn at a single actuation of the roll and the distance between the perforations in the roll practically coincides with the length that may be withdrawn at a single actuation.

It is to be noted however that when a roll is first placed in position on the spindle a single rotation thereof will deliver a greater length of paper than when the roll has been partly used up. The endwise travel of the roll however must be sufficiently great to allow a full length of paper to be withdrawn from the roll when at its smallest diameter.

When the removed portion is torn from 5 the roll at the perforation, the roll immediately turns to its original position by reason of the action of the spring 9 which has been placed in a state of compression by the withdrawal of the sheet and to prevent sudden jar by the action of the spring 9, have provided a spring 10 upon the outer end held in place thereon by a washer l1 and Cotter-pin 12. Therefore when the roll flics back under the action of the spring 9 it is brought to a stop by reason of the spring l0 engaging the end of the bearing 7 which prevents breakage.-

As the roll returns to its original position under the action of the spring 9, it rotates in the opposite direction from which it ro tated during the removal of: the shoot and to prevent the paper from becoming loosened on the roll l have provided a har lil which may be conveniently formed of a single piece of wire having` substantially the shape shown and pivotally attached to the (i ll lob ll t) Ail' bil

BEST AVAILABLE CCPE bracket 1, which simply lies against the roll` and prevents the paper.l from unrolling dur-V ing the backward rotation of the roll when .returning to its original position.

its shown more particularly in Fig. 2, that end of the paper spindle 4t, opposite `the end in which the rod 5 is inserted, is preferably provided with a square tube 15 in which the square shaped end portion 16 of the saiiidle 17 en ages. The spindle is provided with a han( wheel 18 and when in position the spindle passes through an opening provided therefor in the end of the pivotcd arm 3 and engages in the tubular socket 15 and the roll may be rotated'by hand whenever it is desired, or becomes necessary by reason of the severed edge of the paper lying at the back of the roll. The spindle 17 is securely held in the paper spindle 4 by means of a spring dog 19 having a down turned end engaging in a circumferential slot 20 in the end 16 of the spindle 17. The dog 19 is positioned within a chamber 21 provided in the spindle and when the roll is in position o-ii tliespindle 4 it is impossible to withdraw this spindle or shaft 17 as the spring dog 19 is covered by the roll and it is therefore impossible to release the dog. When the paper has been fully removed from the core the core may be torn from the spindle, the spring catch 19 disengaged from the slot 20, and the end 1G removed from the socket 15, whereupon the bracket 3 may be raised as shown by dotted lines in Fig. 1. The core may then be removed from the spindle and a new roll placed thereon. 'tiiliereupon the bracket is brought to the desired position aiid the spindle 17 placed into position as shown in Fig. 2. The squared end of the spindle is larger than that portion engaging in the aperture in the arm and the spindle is therefore held in the arm when withdrawn from the socket and the arm raised as sliowli by dotted lilies in Fig. 1. The end of the arm 3, pivoted to the bracket 1, is provided with a squared portion 22 which, when the bracket is in its normal position as shown by full lilies in Fig. 1, engages agailist the vertical face of the bracket 1, thereby properly supporting the spindle 17 in its required position. The rcud of the arm is rounded at 23 to allow it to be raised, as shown by the dotted lines.

As the paper is withdrawn from the roll t and the spring 9 compressed, considerable resistance to motion would be developed between the end of the spring and the end of the enlarged portion 4 of the paper roll spindle and to obviate this diliiculty I have inserted therebetween a ball thrust bearing Q-t in order that the parts may operate with as little friction as possible.

From the foregoing description it becomes evident that the device is inexpensive to manufacture, consisting of but few parts that arereadily assembled even by a noliyskilled. mechanic, that a waste of paper is prevented and a greater length of paper than is necessary can not be withdrawn at any single actuation of the roll.

t is also evident that this device may be made in various sizes for various purposes without departing from the spirit et this invention.

Having thus briefly described my inven tion and its mode of operation, what l claim ls 1. In a paper roller, a bracket, a paper roll spindle supported in the bracket. means whereby rotation of the roll and spindle pro duces a longitudinal movement thereof, and a spring tending to resist said longitudinal movement and adapted to return the roll and spindle to its original position when released, the arrangementof parts being such that the longitudinal movement of the roll is limited.

2. In a paper roll holder, a bracket, a paper roll spindle supported in the bracket., means whereby rotation of the roll and s indle produces Va longitudinal movement t iereon, a spring tendiner to resist said loir gitudinal movement anti adapted to ret-urn the roll to its original )ositon when re leased, and a shock absorbing butler on the spindle, the arrangement oi" parts being such tiat the forward rotation of the roll and spindle is limited whereby a specified poi tion only of the paper roll may be unwound at a single actuation of the roll.

3. In a paper roll holder, a bracket., a paper roll spindle carried by the bracket, said spindle being formed of separable parts, means whereby rotation of the roll and spindle produces a longitudinal movement thereof, a coil spring placed under compression by said longitudinal movement which is limited thereby, and means for holding). the separable parts of the spindle in operatable relation.

4. In a paper roll holder, a bracket provided with a fixed and )ivotcd arm, a sepa rable paper roll spindle carried by said arms, a spiral groove formed in that por tion of the spindle supported in the fixed arm, a pin in the fixed arm engaging in said groove, a coil spring on the spindle adapted t0 resist longitudinal movement thereof and to return the spindle to its origt nal position when released, a. spring bumper to relieve the shock incident to the return movement of the spindle, means for holdingA the separable parts in operative relation, said means being inclosed by the paper roll, and a pressure bar for preventing unwinding of the roll during its return movement.
